Angular dependence of Raman spectra in ZnGeP₂ crystal: symmetry analysis and determination of Raman tensors components

The results of an experimental study of the angular dependence of the intensity of polarized Raman spectra of a ZnGeP₂ crystal for the [001] orientation are presented. Based on the experimental data, the components of the Raman tensors for the A 1, B 1, B 2 modes are reconstructed. The experimentally measured dependences in the polarized spectra are compared with theoretical predictions, which made it possible to unambiguously identify the symmetry of the vibrational modes. The presented results can be further used to analyze defects in ZnGeP₂ crystals.
